Design Principles of Pancreatic Islets: Glucose-dependent Coordination of Hormone Pulses [PDF]
, 2015 Pancreatic islets are functional units involved in glucose homeostasis. The multicellular system comprises three main cell types; $\beta$ and $\alpha$ cells reciprocally decrease and increase blood glucose by producing insulin and glucagon pulses, while ...

Substantially increased sensitivity of the spot-ELISA for the detection of anti-insulin antibody-secreting cells using a capture antibody and enzyme-conjugated insulin [PDF]
, 1990 This paper describes an antibody capture spot-ELISA for the detection of anti-insulin antibody-secreting cells. The assay is based on the binding of secreted antibodies by immobilised isotype-specific capture antibodies and subsequent detection of ...

In vivo expression and functional characterization of the zinc transporter ZnT8 in glucose-induced insulin secretion. [PDF]
, 2006 International audienceInsulin-secreting pancreatic beta cells are exceptionally rich in zinc. In these cells, zinc is required for zinc-insulin crystallization within secretory vesicles.

Nestin Action During Insulin-secreting Cell Differentiation [PDF]
Journal of Histochemistry & Cytochemistry, 2010 Nestin, which was initially identified as a marker of neural stem cells, has been reported in regenerating pancreas as well as in early embryonic stem (ES) cell derivatives. However, little is known about its specific roles in stem cells as a functional regulator.

Recombinant Incretin-Secreting Microbe Improves Metabolic Dysfunction in High-Fat Diet Fed Rodents [PDF]
, 2017 peer-reviewedThe gut hormone glucagon-like peptide (GLP)-1 and its analogues represent a new generation of anti-diabetic drugs, which have also demonstrated propensity to modulate host lipid metabolism.

Glucose represses connexin36 in insulin-secreting cells [PDF]
Journal of Cell Science, 2005 The gap-junction protein connexin36 (Cx36) contributes to control the functions of insulin-producing cells. In this study, we investigated whether the expression of Cx36 is regulated by glucose in insulin-producing cells. Glucose caused a significant reduction of Cx36 in insulin-secreting cell lines and freshly isolated pancreatic rat islets.

β-Cell Replacement Strategies: The Increasing Need for a “β-Cell Dogma”
Frontiers in Genetics, 2017 Type 1 diabetes is an auto-immune disease resulting in the loss of pancreatic β-cells and, consequently, in chronic hyperglycemia. Insulin supplementation allows diabetic patients to control their glycaemia quite efficiently, but treated patients still ...

Cyclic AMP signalling in pancreatic islets [PDF]
, 2010 Cyclic 3'5'AMP (cAMP) is an important physiological amplifier of glucose-induced insulin secretion by the pancreatic islet β-cell, where it is formed by the activity of adenylyl cyclases, which are stimulated by glucose, through elevation in ...

Glucocorticoids Reprogram β-Cell Signaling to Preserve Insulin Secretion [PDF]
Diabetes, 2017 Excessive glucocorticoid exposure has been shown to be deleterious for pancreatic β-cell function and insulin release. However, glucocorticoids at physiological levels are essential for many homeostatic processes, including glycemic control. We show that corticosterone and cortisol and their less active precursors 11-dehydrocorticosterone (11-DHC) and ...
